Celga is great I use them all the time, but you 
can bid real time with Rinkya!  Eventhough 
Rinkya's fees are higher, sometimes it is worth 
it because you're able to 'Buy it Now' with the 
Rinkya system, rather than sending an email to 
Celga or any other deputy service and crossing 
your fingers in hopes that they see it in time!
